Hello people i'm new here,so kid gloves ok!,
nice easy one for you...i'm working with 12v 2a dc RGB led 5metre strips,I get 2 projects out of each 5 metre reel (1 from each end of the reel,having a 4pin connector attached),leaving me with roughly a metre offcut from the middle depending on the size of the other projects.
Now I want to use these offcuts to create smaller projects but I want them to be battery powered....I have 6v battery holders,but they power only the red led's on the strip.......is it possible to power these offcuts with 6v and make all the led's light?
Thanks for any advice

 

It's impossible to give you a solid answer without knowing the details of the strips you are talking about. If the LEDs of a given color are in series and the total consumption of all three strips is up to 2A, then your strip fragments are going to take that same amount of current (but at a lower voltage) which is going to drain your 6V battery (if I'm right and thinking that you are talking about a battery holder that holds 4 AA, C, or D cells) quite quickly.

 

12V light strips probably have 3 LED's in series so with whit LED's firstlight might be at about 9V.
